IMPROVEMENT IN WATER-WHEELS.

specification forming part of Letters Patent No. 58,008, dated September11, 1866.

To all whom it may concci'n:

Be it known that I, JOHN S. WARREN, of Port Chester, in the county ofWestchester and State of New York, have invented a new and ImprovedWater-Vl'heel and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable those skilled inthe art to make and use the same, reference being had to theaccoinpanyingdrawings,forining part of this specification, in which-Figure 1 is a side sectional view of my invention, taken in the line xx, Fig. 2; Fig. 2, a horizontal section of the same, taken in the line yy, Fig. 1.

Similar letters of reference indieate corresponding` parts.

This invention relates to a new and improved horizontal water-wheel; andit consists in a novel construction of the scroll and wheel, ashereinafter fully shown and described, whereby the water is allowed topass through the wheel with less interruption than hitherto, and withless friction, and a greater percentage of the power of the waterobtained.

A represents the scroll of the wheel, which is of curved formtransversely, so as to avoid all angles, as will be seen by referring`to Fig. 1, the top, bottom, and side forlning a curve, and not, ashitherto, coinposed of planes to form an gles at their junction; Thisscroll rests upon suitable supports B, attached to a spider, U, at thecenter of which the bearing or step D for the lower end of thewheel-shaft E is fitted.

F is the wheel, composed of an upper and lower annular plate, a a',buelet-s b, and a hub, c, the upper plate, a, being` inclined, fornning`the frustum of a hollow cone, and the lower plate, a', being` inclinedin a reverse direction, forming the frustuin of an inverted hollow cone.(See Fig.1.) These plates a a fit as snugly as may be within the upperand lower parts of the scroll.

The buckets b have a radial position in the wheel, and they are planesfitted vertically in the wheel, and having their outer edgesfiush withthe peripheries of the plate a ct'. The inner edges of the buckets arescooped or scal' loped out at their upper and lower parts above andbelow the hub, as shown in Fig. 1, so as to allow a free escape for thewater at the top and bottoin of the wheel. The inner edges of thebuckets are iitted in the hub c, and their upper and lower edges fittedin the plates aa'.

The water is admitted into the scroll A through an induction passag'e.Gr, provided with a gate, H, which is secured to a Vertical shaft, I,extending up through the top of the inner end of the passag'e G at itsjunction with the scroll, vand having a hand-wheel or button, on itsupper end for the convenience of turning the shaft I and opening' andclosing the gate H. This induction-passage G is of cylindrical form.

The upper part of the wheel-shaft E has its bearing` J fitted in aspider, K, secured on the top of the scroll.

The advantage of this invention consistsin the free or unobstructedpassage of the water through the wheel, there being no anglcs or cornersin the scroll to iinpede the flow of the water, while theJ upper andlower inclined or conical plates of the wheel, with the scalloped inneredges of the buckets, adxnit of the free escape of the water from thewheel through the centersl of the plates a a'.

Having thus described myinvention, Iclaiin as new and desire to secureby Letters Patelit- The upper and lower inclined or conical plates a a'of the wheel, with the buckets Z), scalloped at their inner edges, incombination with the scroll A, all arra-nged substantially as and forthe purpose specified.

JOHN S. WARREN.
